I have observed a goju stylist use a very simular technique on the block/ side kick to the inside knee taken from one of the kata's they practice.Whipping action at the end ? White crane? (just guessing) influence on his analysis of naihanchi?

I am also picking up that naihanchi might also have been taught in the goju curriculem at some time. Be this true or not , not sure yet.

Undoubtdly Miyagi Sensei studied Niafanchi and other kata. To my best knowledge it was never part of the Goju kata he taught. On the other hand his friend Mabuni trained under both Hiagonna and Itosu, did include it in his Shito Ryu (really covering the full range of Okinawan experience).

So some who teach Goju may have made smiliar journeys and added it to their teaching, but IMO it's non-standard as a Goju tradition.

But as for movements, most movements can be found in most systems, depending on how you define movements.

Loved the video itself of Neihachi Shodan but would have been far, far happier if it were massively slowed down.

Beautiful art, what I could actually SEE of it. (In a too fast way)

Hi Jeff.A very quick students guess.The first defence to my student eye looks like the use of

Natural stance then using tai sabaki

Jump to the left side 45 degreesin to naihanchia To avoid the punch.

(More than likely comes from using cat stance to 45 degree naihanchi from pinan study)

Defenders left arm is raised then using a whipping motion left hand palm heel strike to the punching arm elbow

followed by

again a wipping motion strike using the hard part of the outside of the right wrist to the fore/arm

Then grab wrist with right hand.Feet to 90 degrees (naihanchi stance) (from where he began) (and using hiki-te) left elbow to the shoulder joint

Moving around the front of opponent, by drawing left foot to right foot, natural stance,

While parrying up now numb arm and changing gripping hand from right hand wrist grip to left hand tricep grip of same punching arm. Then right foot out to opponents left side again 45 degrees in-to naihanchi stance using the push from the rear leg (and again hiki-te) to power a whipping motion forearm strike to attackers face.

Using hiki-te(pulling) and spring energy( bouncing off the face) from the forearm strike and changing stance to front stance whichpowers an elbow to the side of the neck

Feet shuffle back to front head crank while adopting a short front stance

The vidoe is fast so cant realy work out if the footwork/ stances are assisting the strikes / head krank.Yet!Could take another look later.
